In general the following rule applies to choosing the speed of your bandsaw blade: The harder the material, the slower the speed; conversely, the softer the material, the faster the speed. When you purchase a Baileigh Industrial Band Saw, there are a lot of things to consider. Band Saw Blades.

When cutting materials other then mild steel other variables come into play. Below is a brief guide to help you pick out the correct TPI saw blade.

I know ideally I should get low TPI blades for thick metal, try not to buy extra blades that I may only use a few times. I don't mind slow. I know if I feed fast, thick metal may over load the teeth and break. I figure if I feed it light, it should cut thick metal just fine. Do I really need low TPI and change blade?

A low tpi blade will work on thick material but you'll have a bad time with the low tpi on thin so I would just buy the high tpi for the majority of the work you'll do and just live with the slower cutting on the thicker material of it only comes up once and a while.

Also keep in mind they are recommending different tooth selections for stationary machines. About the finest tooth pattern they recommend is the 10 - 14 tooth variable pitch blade. Having said that I use their 10 - 14 pitch bimetal blades on everything from soup to nuts. That includes all different materials from aluminum to tool steel, and rectangular pieces up to 6"x6" and rounds of the same diameter. Cutting is slower on the larger pieces, but the blades seem to hold up well.

You might want a more aggressive blade for a portable unit since you'll be holding the saw for the entire cut. The finer ones work for me primarily because I can do the setup and walk away. When the cut is finished I come back and either reset it for another cut, or pick up the finished piece.

I just went through the samething. I bought a Portaband saw just after Christmas with some gift cards. I was using my 4. It was working fine but the cost of the wheels was adding up, so I decided to get a Portaband to take the place of using the cutoff wheels. I picked up a 3 pack of pitch Morse bimetal blades when I bought the saw. The saw worked great!

Cut straight and didn't seem to have a problem getting through the steel, but the blades didn't last long. The teeth on the blades seem too just strip right off the blade after a couple dozen cuts. I thought right off the bat it was poor quality blades. So I went to Fastnal and bought 18 tooth Lenox bimetal blades and they work great. I know I have at least 4 times the cuts on one of the 18 tooth blade then the tooth blades.

So it seems that the correct toothed blades seems to matter more with a Portaband. If you need some down to earth info on blades from an expert contact Tom at Blue Ribbon Abrasives.

With a portaband when your blade is coarser than optimal less than 3 teeth in the cut at one time you can angle the blade to the work so the work appears thicker.
